# Looking

Your package has something to do with unzipping. Find out more:
|
||||
|
||||
> apropos unzip

# Libraries
|
||||
|
||||
Libraries under /lib/ typically contain an .so suffix when they're dynamic. It means 'shared object' as a number of programs will refer to it.
|
||||
|
||||
Others will have an /a/ suffix, meaning that they're static, and will be loaded at runtime.
|
||||
|
||||
We can check the dependencies of a program using the ldd command upon anything in a library. For example:
|
||||
|
||||
> ldd/usr/bin/md5sum
|
||||
|
||||
... shows us that md5sum depends upon:
|
||||
|
||||
- linux-vdso.so.1
|
||||
|
||||
- libc.so.6
|
||||
|
||||
- lib64/ld-linux-x86-64.so.2
|
||||
|
||||
To list all libraries, run:
|
||||
|
||||
> ldconfig -p
|
||||
|
||||
For example, if looking at /usr/lib/x86_64-linux-gnu/libXcomposite.so.1, we might wonder what it's for. We can then run:
|
||||
|
||||
> ldconfig -p | grep libXcomposite
|
||||
|
||||
... and find out nothing except that it redirects /usr/lib/x86...
|
||||
|
||||
So at least we know where it is.
|
||||
|
||||
> ldconfig -p | grep usb
|
||||
|
||||
... this will show where things which nominally relate to usbs live.
|
||||
|
||||
You can add to the libarary path by putting just any text file in /etc/ld.so.cache, e.g. in Arch where the path to the fakeroot environment is placed there.

# Login
|
||||
|
||||
All shells launch either as login or non-login. All remote sessions without a GUI withl require authentication, and therefore will be login.
|
||||
|
||||
## Login
|
||||
|
||||
These shells start by reading /etc/profile then the first of ~/.bash_profile, ~/.bash_login or ~/.profile, and load all given values.
|
||||
|
||||
## Non-Login
|
||||
|
||||
Non-login shells will read /etc/bash.bashrc and then the ~/.bashrc file. You can summon the different shell perameters with the command `.`.
|
||||
|
||||
For example, so summon the file ~/.bashrc, you can perform:
|
||||
|
||||
`. ~/.bashrc`
|
||||
|
||||
How the logout is handled depends upon ~/.bash_logout
|
||||
|
||||
# Defaults
|
||||
|
||||
The default shell config files to create for a new user are under /etc/skel.
|
||||
|
||||
# Shellcheck
|
||||
|
||||
Run `shellcheck script.sh` on your scripts to check them for mistakes.

Install unison on both machines, and on both make the `~/.unison` directory.
|
||||
|
||||
Make a job called `backup`:
|
||||
|
||||
> vim ~/.unison/backup.prf
|
||||
|
||||
All jobs must end in `.prf`.
|
||||
|
||||
Here is an example job, which synchronizes the `~/music` directory with a remote machine.
|
||||
|
||||
```
|
||||
auto = true
|
||||
root=/home/ghost
|
||||
root=ssh://ghost@192.168.0.10//home/ghost/
|
||||
|
||||
path=music
|
||||
|
||||
ignore=Name *.flac
|
||||
|
||||
```
|
||||
The last command means it will ignore any file with a name ending in `.flac`.
|
||||
|
||||
Add a port with this line:
|
||||
|
||||
```
|
||||
sshargs=-p 4444
|
||||
```
|
||||
|
||||
## Automatic Runs
|
||||
|
||||
The first command means this will run but also confirm which files will be deleted, and which will be transferred, us `batch = true` instead.
|
||||
|
||||
Set unison to run with crontab or a systemd unit file to have directories synchronize automatically.
|
||||
|
||||
|
||||
## Problem Solving
|
||||
|
||||
Unison is extremely sensitive to version changes.
|
||||
Both machines must have exactly the same version of unison installed, as well as the same version of `ocaml`.
|
||||
|
||||
Check with:
|
||||
|
||||
> unison -version
|
||||
|
||||
You will see data files summarizing what has happened in the `~/.unison` directory.
|
||||
If something goes wrong, you may be prompted to delete these to start again.

Switch to root to make things easier.
|

|

> yay -S
|
||||
|
||||
> export TASKDDATA=/var/lib/taskd
|
||||
|
||||
Edit `/usr/share/doc/taskd/pki/vars` so that ``CN'' = the hostname (IP is fine).
|
||||
|
||||
> cd /usr/share/doc/taskd/pki
|
||||
|
||||
Execute the `generate` file to generate a selfsigned certificate for the server. These will be \*.pem-files. Copy all \*.pem-files to /var/lib/taskd.
|
||||
|
||||
Make sure a copy of ca.cert.pem remains to generate user-certificates later.
|
||||
|
||||
# Taskd Configurations
|
||||
|
||||
> taskd config --force client.cert $TASKDDATA/client.cert.pem
|
||||
|
||||
> taskd config --force client.key $TASKDDATA/client.key.pem
|
||||
|

> taskd config --force server.cert $TASKDDATA/server.cert.pem

> taskd config --force server.crl $TASKDDATA/server.crl.pem
|
||||
|
||||
> taskd config --force ca.cert $TASKDDATA/ca.cert.pem
|
||||
|
||||
# Change Taskd Log Location
|
||||
The default is /tmp/log, which obviously you don't want.
|
||||
|
||||
> touch /var/log/taskd.log
|
||||
|
||||
> chown taskd:taskd /var/log/taskd.log
|
||||
|
||||
> taskd config --force log /var/log/taskd.log
|
||||
|
||||
Finally, set up the servername - the same one as in the certificates. Mine is ``testarch''.
|
||||
|
||||
> taskd config --force server testarch:9001
|
||||
|
||||
# Adding users
|
||||
Let's add the group ``home'', then the user ``ghost'', will go in that group.
|
||||
|
||||
> taskd add org home
|
||||
|
||||
> taskd add user home ghost
|
||||
|
||||
`3f9e6154-25cb-4e45-88bb-45e98feef904`
|
||||
|
||||
> taskd add user home alfred
|
||||
|
||||
`4fbb319c-c493-437a-ab7a-028f5b75e522`
|
||||
|
||||
The user then gets a key.
|
||||
|
||||
Finally, make sure that taskd can read its own data>
|
||||
|
||||
> chown -R taskd:taskd /var/lib/taskd/orgs
|
||||
|
||||
... or perhaps the entire directory of /var/lib/taskd/.
|
||||
|
||||
Then it's back to /usr/share/doc/taskd/pki
|
||||
|
||||
Generate some userfiles:
|
||||
|
||||
> ./generate.client ghost
|
||||
|
||||
> ./generate.client alfred
|
||||
|
||||
The bob and ghost \*pem files have to be added to the given users' home directories.
|
||||
|
||||
# Setting up Users
|
||||
|
||||
> sudo apt-get install taskwarrior taskd
|
||||
|
||||
> task
|
||||
|
||||
Then move the \*pem files into the .task directory of the user.
|
||||
|
||||
Don't forget to add the ca.key.pem from `/usr/share/doc/taskd/pki`!
|
||||
|
||||

# User Defines Attributes - UDA
|

|

Each UDA has two to four attributes: type (numeric or string) and label are necessary:
|
||||
|
||||
> task config uda.THING.type {numeric,string}
|
||||
|
||||
> task config uda.THING.label Thg
|
||||
|
||||
Constrain these attributes to a comma-delineated set with:
|
||||
|
||||
> task config uda.THING.values brown,orange,green
|
||||
|
||||
You can also show how important the Attribute makes something:
|
||||
|
||||
> urgency.uda.THING.coefficient=2.8

# Aliases

# Designate DNS
|
||||
|
||||
On Debian, a file might gain DNS services by adding the following to /etc/network/interfaces:
|
||||
|
||||
```
|
||||
|
||||
auto eth0
|
||||
iface eth0 inet static
|
||||
address 10.0.0.23
|
||||
netmast 255.255.255.0
|
||||
gateway 10.0.0.1
|
||||
dns-nameservers 208.67.222.222 208.67.220.220
|
||||
dns-search example.com
|
||||
|
||||
```
|
||||
|
||||
# URL Aliases
|
||||
|
||||
To change where hosts go, edit /etc/hostnames. You can enter, e.g.:
|
||||
|
||||
`54.239.25.200 www.amazon.com a`
|
||||
|
||||
... which then means simply the letter 'a' will lead you to amazon.com.

# Intro
|
||||
|
||||
This is a basic Linux firewall program.
|
||||
|
||||
Look at your firewalls:
|
||||
|
||||
> iptables -L
|
||||
|
||||
We see the output of input, output and forwarding rules.
|
||||
|
||||
# Forward
|
||||
|
||||
I don't need any forwarding, so I'm going to drop all forwarding:
|
||||
|
||||
> iptables -P FORWARD DROP
|
||||
|
||||
# Input
|
||||
|
||||
Let's 'A'dd, or 'A'ppend a rule with -A. Let's drop all input from a nearby IP
|
||||
|
||||
> iptables -A INPUT -s 192.168.0.23 -j DROP
|
||||
|
||||
Or we can block all input from a particular port on the full network.
|
||||
|
||||
> iptables -A INPUT -s 192.168.0.0/24 -p tcp --destination-port 25 -j DROP
|
||||
|
||||
> iptables -A INPUT --dport 80 -j ACCEPT
|
||||
|
||||
|
||||
This allows http traffic to an Apache web server over port 80.
|
||||
|
||||
However, rules are accepted in order - so a packet cannot be rejected and then accepted.
|
||||
|
||||
To delete rule 2 from the INPUT chain:
|
||||
|
||||
> iptables -D INPUT 3
|
||||
|
||||
Alternatively, you can 'I'nsert a rule at the start, rather than 'A'ppending it.
|
||||
|
||||
> iptables -I INPUT -s 192.168.0.13 DROP
|
||||
|
||||
# Catchalls
|
||||
|
||||
Catchall rules state that anything which is not permitted is forbidden. They must be allowed last.
|
||||
|
||||
# -Jurice-Diction
|
||||
|
||||
The -j flag accepts ACCEPT/REJECT/DROP. The last two are identical except that "REJECT" acknowledges the rejection.
|
||||
|
||||
Flush all existing rules with:
|
||||
|
||||
> iptables -F

Debian has a long, boring setup.

> curl -sSL https://install.pi-hole.net | PIHOLE_SKIP_OS_CHECK=true sudo -E bash
|
||||
|
||||
# Setup
|
||||
|
||||
> sudo usermod -aG pihole $USER
|
||||
|
||||
Remove that google dns server.
|
||||
|
||||
> pihole -a setdns 9.9.9.9 1.0.0.1
|
||||
|
||||
Disable pihole password by setting a blank password.
|
||||
|
||||
> pihole -a -p
|
||||
|
||||
Get a new list of blocked domains, then reload:
|
||||
|
||||
> pihole -g -r
|
||||
|
||||
Every so often, run `pihole -g` again (perhaps put it in crontab).
|
||||
|
||||
## Check the Pihole
|
||||
|
||||
Observe the pihole's output while you ask it a question:
|
||||
|
||||
> pihole -t
|
||||
|
||||
Then ask the question from another computer:
|
||||
|
||||
> dig @[ pihole ip ] archlinux.org
|
||||
|
||||
## System-Wide Setup
|
||||
|
||||
To make the pihole work for the entire Network, enter your router and set the DNS server as nothing but your pihole.

Next up, visualizations with vis in another screen. ^S makes a horizontal split and you can switch into that with ^tab to name is 'visualizations' and start vis. Switch back to the first screen and make another horizontal split and a screen in there with the name 'reading'. Inside reading you type ^? to get a list of useless screen commands. Reading can then be detatched with ^d and the horizontal split destroyed with ^X.
|
||||
|
||||
Those visualizations should be larger, so we enlarge them with Ctrl+: to send the command resize 50 and :resize -h 100.
|
||||
|
||||
Once done with reading, you can destroy it wil ^k then destroy the lot once done with ^\. Outside the screens entirely you can ensure complete death with 'killall screen'.
